Question 6, 7, 8, 9 and 10 are about the following problem (similar to the one in my video lecture) valves is the Western, which has an annual demand of 4,000 units. The cost of each valve is $90.00, and the inventory carrying cost is estimated to be the she has concluded that the average ordering cost is $25.00 per order. Furthermore, it takes about 8 work days for an order to arrive from the supplier. During this time, the demand per week (= 5 work days) for Central's valves is approximately 80 . Assume there are 250 work days per year. What is the reorder point?
